Yet, when the results of a particle collision are detected, they are invariably in the form of linear tracks (see, for example, the illustrations accompanying the article on bubble chambers).

The first high-energy particle collisions are scheduled for the first quarter of this year.

Shears stressed that the results were preliminary and far more particle collisions need to be analysed to be certain of the result.

Antiparticles are created everywhere in the universe where high-energy particle collisions take place.

The coherence can be disrupted by other interactions, such as particle collisions and energy transfer, and so often require high intensity radiation to be sustained.
